quitting smoking

any tips? I've gone from 40 cigs/day to 5, but I wanna quit for good
not smoking for long periods doesn't stress me out like it used to
the few cigs I smoke are purely out of habit (after waking up, after lunch, waiting for the train occasionally, after diner and before I go to sleep) and they make me feel like shit :\
I should really seize the opportunity to quit now because I fear I will soon start smoking 10 cigs/day, then 15, then 20 etc.
I just can't break the habit :(

thanks for the support, anons
you encouraged me to throw away my last 1/2 pack of cigarettes and my lighter

let's see how this works out, i'm actually looking forward to not smoking anymore and saving €100/month because of it. if i can keep it up for a year i can buy a ps3 and a hdtv from the money i saved!

i'll keep you updated
